Vacuum Insulated Pipe is often referred to as Vacuum Jacketed Piping (VJP), Static Vacuum Insulated Piping (SVIP), Dynamic Vacuum Insulated Piping (DVIP), or Flexible Vacuum Insulated Piping (FVIP). However you say it, we’ve got you covered.
Here at CryoWorks, we make things happen – all tailored to your project specifications, needs, and budget.
A vacuum insulated field can joint is a welded assembly that utilizes a jacket field can to create a continuous vacuum jacket along the connection of two factory-sealed vacuum insulated piping sections. Vacuum insulated field can joints provide a low heat-leak transition between the outer jacket and the inner pipe. Once the inner process pipe is welded and inspected, the exposed inner line is wrapped with super-insulation, gettering is installed, and the field can slides into place. The field can is then welded on the ends and pumped down to a high-vacuum level to ensure minimal heat leak.
Typically, vacuum insulated field joints are used in place of bayonet connections when the pressure ratings of the piping system exceed that of standard bayonet connections as well as in larger bore piping systems when bayonets are not available. CryoWorks can also accommodate vacuum insulated field can joints at tees, elbows, and valves. Installation should be completed by CryoWorks technicians or certified welders trained in cryogenic and vacuum installations.
